ST6208C/ST6209C/ST6210C/ST6220C
1 INTRODUCTION
The ST6208C, 09C, 10C and 20C devices are low
cost members of the ST62xx 8-bit HCMOS family
of microcontrollers, which is targeted at low to me-
dium complexity applications. All ST62xx devices
are based on a building block approach: a com-
mon core is surrounded by a number of on-chip
peripherals.
mable option bytes of the OTP/EPROM versions
in the ROM option list (See Section 11.6 on page
96).
The ST62P08C/P09C/P10C/P20C are the Factory
Advanced Service Technique ROM (FASTROM)
versions of ST62T08C, T09C, T10C and T20C
OTP devices.
The ST62E20C is the erasable EPROM version of
the ST62T08C, T09C, T10C and T20C devices,
which may be used during the development phase
for the ST62T08C, T09C, T10C and T20C target
devices, as well as the respective ST6208C, 09C,
10C and 20C ROM devices.
They offer the same functionality as OTP devices,
but they do not have to be programmed by the
customer (See Section 11 on page 90).
These compact low-cost devices feature a Timer
comprising an 8-bit counter with a 7-bit program-
mable prescaler, an 8-bit A/D Converter with up to
8 analog inputs (depending on device) and a Dig-
ital Watchdog timer, making them well suited for a
wide range of automotive, appliance and industrial
applications.
OTP and EPROM devices are functionally identi-
cal. OTP devices offer all the advantages of user
programmability at low cost, which make them the
ideal choice in a wide range of applications where
frequent code changes, multiple code versions or
last minute programmability are required.
For easy reference, all parametric data are located
in Section 11 on page 90.
The ROM based versions offer the same function-
